Weather in September
Temperature
As August transitions into September, the average high-temperature rests at a still tropical 86.9°F (30.5°C), maintaining a close resemblance to the previous month. The temperature dips to an average of 75°F (23.9°C) during September nights.Heat index
In September, the heat index is computed to be a very hot 100.4°F (38°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
